Help me find a long, wool winter coat

[WildPatience]

I've had enough of wearing my puffer coat all the time and want a classic long, wool coat that I'll hopefully have for years. Budget up to around £400.
Looking for something with over 50% wool, below knee-length (I'm average height) in camel, brown or grey. Dropped shoulders and must have buttons but a belt as well would be ideal.
I like this style but would prefer a plain colour. https://www.wolfandbadger.com/uk/coat-bologna-italian-wool-mix/

Any suggestions?

Check out the charity shops and eby/vinted etc. Have bought some beautiful wool coats for £20-30

What dress size?

This. I saw a wool and cashmere coat in a charity shop for under £30. The quality from yesteryear is in my opinion better than the stuff being produced now.

I got a lovely one from Hobbs last year following a recommendation on here!

I got this one recently and have been really pleased with it.

Jigsaw have a few left in the sale

Thanks - I would ideally do this but charity shops near me are not great and I have very limited time. I've had bad luck with Vinted but maybe I'll try again.

Karen Millen have some good quality wool coats, quite a few in the sale worth having a look at, also Hobbs, Reiss, Whistles & jigsaw
